[0028] The top of the positioning member 22 is provided with a positioning plate 221 with a groove, one end of the clamping member 23 is provided with a material clamping plate 231 with a groove, and the other end of the clamping member 23 is provided with a connecting plate 232; the buffer member 24 includes a buffer cylinder 242 and a buffer plate 241, the buffer cylinder 242 is connected to the buffer plate 241, and the buffer plate 241 faces the clamping member 23; the tensioning member 25 includes a connecting rope 252, a weight 253, and a guide roller 254, one end of the connecting rope 252 is connected to the weight 253, the other end of the connecting rope 252 is connected to the connecting plate 232, and the connecting rope 252 is located on the guide roller 254;

[0029] The material turning mechanism 3 comprises a material turning cylinder 31 , a rotating shaft 32 , and a material hook 33 . The material turning cylinder 31 is connected to the rotating shaft 32 , and the rotating shaft 32 is connected to the material hook 33 .

[0030] like Figure 6 As shown, the control line 4 includes a sleeve 41 and a steel rope 42. The steel rope 42 needs to be stretched by a preset tension according to parameters, so as to test the length of the steel rope 42 extending out of the sleeve 41 under different tension values.

[0031] In the control line testing device of the utility model, the testing mechanism 2 divides the table top of the workbench 1 into a loading area 11 and a qualified product collection area 12, and the bundled control lines 4 are placed in the loading area 11, so as to facilitate the loading of each line; a single control line 4 is horizontally placed on the material hook 33, the end of the sleeve 41 is clamped on one side of the grooved positioning plate 221, the steel rope 42 passes through the groove, and the protruding end of the steel rope 42 is clamped in the groove of the grooved clamping plate 231, so as to complete the positioning of the control line 4; the two ends of the clamping member 23 are respectively connected to the steel rope 42 and the weight 253, and the weight 253 of corresponding mass is set according to the test parameter requirements, and the gravity of the weight 253 provides a pulling force to the clamping member 23, and the clamping member 23 moves linearly along the slide rail 21, driving the steel rope 42 to stretch, and the clamping member 23 measures the displacement distance through the grating ruler 27 , thereby detecting the stretching value of the steel rope 42; the value measured by the grating ruler 27 is uploaded to the terminal. When the test result is qualified, the terminal issues an instruction to the turning cylinder 31, the rotating shaft 32 rotates, the material hook 33 is turned over, the control line 4 on the material hook 33 is lifted, the steel rope 42 escapes from the grooved clamping plate 231 and the grooved positioning plate 221, and is turned over to the qualified product collection area 12; when the test result is unqualified, the turning cylinder 31 remains in a standby state, and the staff is required to manually put the unqualified products on the material hook 33 into the defective product collection box 13. The sensor 14 in the box can be an existing photoelectric sensor. After receiving the instruction from the terminal, the sensor 14 will sense whether the material is fed. If the material is not fed, the testing mechanism 2 cannot be started, so as to prevent the operator from missing defective products or mixing defective products with qualified products.

[0032] The unloading opening of the defective product collecting box 13 is provided with a door panel 15, and the door panel 15 is provided with a buckle 16. When the defective products are put into the box, the door panel 15 closes the unloading opening through the buckle 16, and when the defective products in the box need to be taken out, the door panel 15 only needs to be opened through the buckle 16.

[0033] The clamping member 23 moves linearly between the positioning member 22 and the buffer member 24 along the slide rail 21. The buffer cylinder 242 of the buffer member 24 controls the extension and contraction of the buffer plate 241, which can play a buffering role to prevent the clamping member 23 from moving quickly or even derailing due to uncontrolled pulling force of the weight 253 caused by operating errors.

[0034] The slide rail 21 is provided with a plurality of adjustment holes 211 along the axial direction. The positioning member 22 and the buffer member 24 can be provided with fixing holes. By passing the fixing holes through the fixing holes with fastening screws (which are prior art and not shown in the figure), the adjustment holes 211 at different positions are selected to adjust the spacing between the positioning member 22 and the buffer member 24 to meet the test requirements of control lines 4 of different lengths and different tensions. And by fixing the positioning member 22 and the buffer member 24 with fastening screws, the sliding of the positioning member 22 and the buffer member 24 during the test can be avoided to affect the test results.

[0035] The tensioning member 25 also includes an I-shaped block 251, which is located at the end of the connecting rope 252; the connecting plate 232 is provided with an I-shaped slot 233, and the block 251 is inserted into the slot 233. This connection method is convenient for replacing weights of different specifications. The weight 253 is drooped through the connecting rope 252, thereby providing tension to the steel rope 42. When the clamping member 23 moves with the weight 253, the connecting rope 252 moves downward on the guide roller 254 at the same time, and the guide roller 254 plays a guiding role. The I-shaped structure of the block 251 and the slot 233 not only facilitates disassembly and assembly, but also improves the stability of the connection between the connecting rope 252 and the clamping member 23. The clamping member 23 and the connecting rope 252 are not easy to be disengaged during the synchronous movement.

[0036] The guide roller 254 is provided with a limiting groove 255 , and the connecting rope 252 moves along the limiting groove 255 . The limiting groove 255 limits the connecting rope 252 , thereby preventing the connecting rope 252 from escaping from the guide roller 254 due to excessively fast movement.

[0037] The control line 4 on the material hook 33 is transferred as the rotating shaft 32 rotates through the material turning cylinder 31. There are several material hooks 33, and a connecting ring 34 is provided at the end of the material hook 33. The connecting ring 34 is sleeved on the rotating shaft 32. Since the weight of the control line 4 is relatively small, on the basis of the support of the positioning member 22 and the clamping member 23, the material hook 33 only needs to be hooked below, and the requirement for the material support strength is not high. It mainly plays the role of turning the material. According to the control lines 4 of different lengths and specifications, the spacing between the connecting rings 34 can be adjusted by moving each connecting ring 34, thereby adjusting the hooking position.

Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all within the scope defined by the claims of this application.
